Concern over the production of hazardous trihalomethanes (THMs) as byproducts of the chlorination of drinking water prompted the examination of the chlorination of naturally occurring aquatic humic acid in the presence of bromide ion. The effect on THM production of varying reaction conditions such as pH, chlorine-to-bromine ratio, and reaction time was investigated using gas chromatography-electron-capture detection. THMs were formed under all conditions examined, the production of highly brominated compounds being favored. © 1992.
